- To all whom it may concern:

spring seat construction. Heretofore spring seats of this class have been constructed either with a wire or a wooden frame having a fabric or leather covering tacked thereto, and the seat springs secured to the frame by means of staples or otherwise. An objection to such a construction has been that when a spring became displaced or broken, it was a diflicult matter to adjust or replace it without dismantling the entire seat. Another objection to such a construction has been that the building of the upholstered portion upon the frame, necessitated the simultaneous mounting and adjustment of the seat springs. With the wire frame construction, the leather was brought around the frame and secured by sewing. The operation of sewing was one which entailed considerable expense, because of the labor thereof. Seats of these constructions have the leather orfabric exposed at the bottom,

where the greatest wear occurs, and for this reason the covering material soon wears out at the edges of the seat frame over which it is tacked. Furthermore the leather or fabric, where it is tacked or sewed upon its mounting frame, frequently tears away, because the tacks or threads will out through the material. I

An object of our invention is to produce an improved spring seat construction, in which the sides and top of the seat may be A further object is to produce a seat spring construction, in which the upholstered portion and the spring portion may be constructed separately, and in which the spring portion may be removably mounted in the upholstered portion.

'A further object is to produce an improved seat construction, in which the edges of the upholstery are clamped to the mounting frame along their entire lengths, in-

inner side of the frame.

stead of being tacked or sewed at intervals, as in ordinary spring seat construction.

I A further object is to produce an improved spring seat construction, in which the upholstery mounting frame is constructed to have its greatest strength in the proper direction for the loads placed upon it, and is reinforced at its edges by means of a metal strip, set on edge, instead of lying flat, as in the wooden stripsof the ordinary spring seat construction.

These and other objects are attained in the spring seat construction described in the following specification, and illustrated in the accompanying drawings, in which,

Figure 1 is a perspective view of the spring seat embodying our invention. Fig. 2 is an inverted plan view of the seat construction embodying our invention. Fig. 3 is a sectional view, taken on the line 3&3 of Fig. 2, upon an enlarged scale. is a fragmental perspective view of a detail of our invention.

The spring seat embodying our invention comprises an upholstered portion 5 and a spring portion 6. The upholstered portion consists of the cushion 7, having depending sides 8 and ends 9, around and inside of the lower edges of which extends a reinforcing spring-mounting metal frame 10. The lower edge of the frame is turned over a wire 11, to form a beaded edge 12, and over this head the thicknesses of upholstery are turned, they being turned in to engage the Over these inturned edges is placed a continuous edging of substantially U-shaped metal molding 13, the edges of which are pressed together upon the upholstery covering, to bind it tightly over the head 12 and against the of the seat'.

means of a series of transversely and lon-.

gitudinally extending wires 21, which prevent displacement of the upper endslof the der surface of the upholstery forming the bottom of the cushion 7 Around the edge of the springs is a heavy wire 22, forming a frame adapted to engage the upholstery forming the bottom of and adjacent to the edge of the cushion. This wire frame holds the cushion out straight and yet permits of the edge thereof yielding to render the seat comfortable. p

No portionf'of the spring construction above described is secured to the cushion or any portion of the upholstery material. The only connection of the spring portion with the upholstered portion, is by means of the removable engagement of the'hooked ends 16 in the loops 15of the upper portion 14 of the frame 10. This construction permits the spring portion to be constructed separately from the cushion 7, which may be formed over the usual shoe or form, and have its mounting frame 10, and its metal clamping molding 13 secured in place before receiving the spring portion.

An advantage attained by our improved spring seat construction over previous constructions, is that the upholsteringis assembled on the frame 10 of the seat, before the springs are inserted, and the sides and top of the cushion can be made of one piece of upholstering material, without necessitating any sewing around the edges of the top by our improved construction, is that the spring portion is constructed separately, it being entirely-assembled before being inserted in the upholstered portion. This permits of the springs being removed in one piece, for purposes of repair, without having to rip the upholstered portion at any point to render the springs accessible.

One ofthe most important features of advantage is the securing of the upholstery at its bottom edge, by means of the clamped molding. This is a most effective way of securing the upholstery at all points around the heading 12 'of the frame 10, since it eliminates the objectionable perforating and consequent weakening of the upholstering material, by the usual sewing or tacking. A further advantage gainedby this molding is that the seat is provided with an entire metal base upon which it rests, thus protecting the upholstery from'wear. The embodiment of a frame consisting of a continuous metal strip, set on edge, with its lower edge reinforced against side bending, by means of a stiffening beading and a cooperating molding, is also an improvement over Another advantage attained ordinary seat frame constructions, in which not desire thereby to limit ourselvesto such.

details, but a I What we claim as our invention is: I v V 1. A spring seat comprising an upholstered portion, anda spring portion, said upholstered portion comprising a cushion located at the top thereof, and a looped frame secured at the bottom thereof, said spring portion comprising a series of springs, and a series of strips having hooked ends, said strips securing the lower ends of the springs thereto and holding the upper ends of the springs in engagement with the cushion when the hooked ends ofv the strips are brought into engagement with the loops of the frame. 2. In combination in a spring seat, an-upholstered portion having a metal frame located at its lower. edge, the edge ofthe upholstery being turned over theloweredge of the frame, and a substantially U-shaped metal edging embracing the overturned edge of the upholstery for clamping the frame and upholstery together, loops formed in the frame, a spring portion comprising a series of springs, and a series of strips for the springs, said strips having hooked ends for removably engaging th loops. e A 3. A spring seat comprising an upholstered portion, and a spring portion, said up-. holstered portion comprising a cushionlocated at its top, and a vertically disposed looped metal reinforcing frame located at its lower edge with its sides engaging the sides of the upholstery, the edges -'of the upholstery being turned over the lower edge of the frame, and a substantially U-shaped sheet metal clamp embracing the lower edge of the "frame and upholstery for clamping the upholstery thereto, said spring portion comprising a series of springs, and a series of strips having hooked ends, said stripssecuring the lower ends of the springs thereto and holding theupper ends of the springs in engagement with the cushion when the 'hooked ends of'the strips are brought into engagement with the loops of theframe.
